Much of Vitro’s work for the client involved pitchwoman “Melanie,” and it culminated in January with a Terminator: Genisys tie-in which may have involved a banner ad that was actually…cool.

A spokesperson for Vitro declined to comment for this post. We have repeatedly reached out to Red Robin’s PR department and received no response.

Multiple sources, however, confirm that the review is ongoing and that Vitro’s fellow MDC Partners shop KBS is one of the agencies pitching.

It’s unclear at this time exactly which parts of the account are involved, but we have reason to believe Vitro may retain the media portion of the business and that it will also continue working on creative campaigns until after the review is complete…which could be several months from now.

In other, stranger Red Robin news, the company recently announced that it would become the first(?) American chain to offer ramen burgers for the meat-averse demographic. (No, this isn’t an April Fools’ joke.)
